GYM a. n 2, ATTORNEY RECORDING APPARATUS This invention relates to ahigh speed recording apparatus capable of recording signal intelligencefrom a cathode ray tube.

BACKGROUND OF THE INVENTION In processing information in numerical,alphabetical or special character form from a computer or other highspeed data source, the weakest link in the final stage of processingsuch data has been the mechanical printers. In order to take fulladvantage of the high speed capability of present day data processingdevices, the output printer for such devices must be equally capable ofhigh speed performance. Many attempts have been made, some successful,to improve the speeds of mechanical printers. However, the very natureof these devices, for example, mechanical inertia sets an upper limit ontheir speed capability.

Conventional printers employ a large number of mechanical printingmembers such as hammers and type members. The useof this kind ofstructure results in printers which are not only bulky but alsoexpensive. In these conventional printing devices, printing is done bymechanical action between the typeforming means and the paper orprintout form. That is, an entire character line is mechanically printedrapidly while the printout form is stopped, then the form is rapidlyadvanced for printing the next succeeding line. For high speed printing,the intermittent movement of the form at a very rapid speed creates verydifficult problems. Additionally, this mechanical action at a high rateof speed causes an undesirable noise level and wear is inherent, thuscausing extensive down-time for replacement and repair of the'mechanical devices.

The present invention is a 10,000 line per minute hard copy printer ofhigh quality which overcomes the aforesaid problems of conventionalprinters. General approaches to accomplish this result would be amongthe following:

1. Mechanical impact or spark discharge type printer with printing on aline increment basis.

2. Mechanical impact or spark discharge type printers but with multipleline units so as to increment mechanically several lines at a time.

3. Full page recording with page incrementing at:

a. full size.

b. micro-image with full size obtained with a reproducer of some sort.

0. intermediate size with full or micro-size obtained by a reproducer orthe like.

4. The same as (3) but line at a time incrementing.

Present day mechanical printer technology limits place carriage advancetime at about 5X10 seconds per line leaving about 1 l0"" seconds toprint a line in system 1) above. It is readily seen that this is not avery feasible system unless it is limited to characters per font orcolumns per page in such a manner as to allow printing in seconds.

System (2) is feasible but costly since multiple print units must beused together with multiple drives. If this system is tied to a computerthe buffering must also be duplicated. Roughly, the increase in costwill be directly proportional to the number of lines printed percarriage advance. Since 1,500 lines per minute is the limit of someknown printers at 10,000 lines per minute (1pm) it could be expected tocost about six times as much. Again, this is not a very good system.

Printers such as system (4) above have the same problems anddisadvantages already mentioned with regard to systems (1) and (2) butto a lesser extent possibly, but now precision incrementing is necessaryfor less than full size format. At full size the same problems aredirectly encountered, as the system is the same as systems l) or (2).

System (3) then remains as the only technically feasible and reasonablypriced system provided that the number of hammers, sparks, gaps, etc.are kept to a minimum. One way in which this can be done is by utilizinga cathode ray tube. The cathode ray tube can I be considered analagousto a single hammer having motion in the X and Y planes.

Present technology using light optics prevents a cathode ray tube systemfrom having good resolution and aesthetic appeal. The reasons for thisare the following:

l. Use of a lens in the micro mode severely limits the ultimateresolution; for example at 15 or 20 reduction the image spread functionis about one-half mil at 50 percent intensity prints. This results inabout 2 or 3 line pairs per millimeter in a character at full sizewhereas 5 to 10 are needed: and

2. A lens between the CRT and the receptor can transmit only about 1 or2 percent of the energy from a CRT. This loss of energy results in theexposure time being unduly long. For single (point) source CRTs thismeans a matrix or vector type of character must be printed. High printerspeed and long exposure time mean that the detailed bits per charactermust be small resulting in poor character appearance. For parallelsource CRT (compositron or charactron) the cathode current orelectro-optic resolution limit resolution or speed so as to eliminatetheir use in this application.

While there are materials with high sensitivity to compensate for lenslosses they are expensive and require considerable processing to developthe latent image. For a commercial system this is a very severedrawback.

The use of a CRT in very near contact or contact with the receptor is afeasible way of overcoming the problem described. This means that theCRT face should be a fiber optic face plate. The system proposed is sucha system. It has the advantage that the time per line advance (beammovement) is about 10 microseconds and the time for page advance is zeroin receptor movement and 10 microseconds approximately in beam movement.

high speed recording apparatus which is mechanically simple andreasonably inexpensive.

BRIEF DESCRIPTION OF INVENTION In a first embodiment of the inventionthe recording apparatus comprises a cathode ray tube having signalintelligence applied to the input circuits thereof. Attached to the faceof the cathode ray tube is a fiber optic plate. The fiber optic plate ispositioned so as to concentrate the light of the cathode ray tube onto aphotosensitive surface or record medium. The photosensitive surfacetakes the shape of an endless belt wrapped around a plurality ofrollers. The rollers are positioned and actuated in conjunction withbeam movement such that a portion of the belt is always in contact withthe face of the cathode ray tube with the result that there is zero pageadvance time. 'Means are provided to develop the image on the belt andto transfer the image to a permanent surface. In a second embodiment ofthe invention the photosensitive surface is fed from a supply reel ontoa take-up reel and is developed either in a vacuum, partial vacuum, orair.

The nature of the present invention having been set forth, there willnow be presented a more detailed description in illustration but notlimitation of the in vention in the following specification and drawingsin which:

FIG. 1 is a schematic view showing the basic elements of the recordingapparatus;

FIG. 2 is a view similar to FIG. 2 showing details of the processingstation; and

FIG. 3 is a view similar to FIG. 1 showing a reel supply record medium.

In FIG. 1 a cathode ray tube 11 converts the signal intelligence frominput circuits into suitable form to create character images on recordweb or belt 16. Input circuits 10 may be responsive to code signals andmay comprise translators, gates, and amplifiers in order to generate thepotentials necessary to produce the character images to be displayed onthe face of cathode ray tube 11. Input circuits 10 may also supplysignals according to a predetermined time base to drive the recordrollers and to initiate the development and transfer station as will bediscussed in more detail hereinafter. It is noted that in lieu ofcathode ray tube 11 other means may be substituted as a signal transducer means. One substitute might be a plurality of electrodes overwhich a record medium is passed. A suitable code system for drivinginput circuits 10 is described in U. S. Pat. No. 2,736,770 to McNaney.Cathode ray tube 11 may employ either electromagnetic or electrostaticdeflection and is of the conventional type except that it is provided atone end with a fiber optic face plate or target screen 12 which issubstantially flat so as to accommodate record web or belt 16. Fiberoptic face plate 12 prevents light dispersion which would occur if thetube target screen were merely a glass face plate. Fiber optic faceplate 12 through which the light image is transmitted is made of abundle of glass fibers extending in a direction parallel to the axis ofthe cathode ray tube. The record web 16 is pressed against the face ofcathode ray tube 11 by a plurality of rollers l, 2, and 6. Where therecord web 16 is a photoconductor it would have a conductive backing ofa flexible conductor such as aluminum and may be given an initial chargeby electrode 18 which is connected to a source of high potential (notshown). A photoconductor is a non-conductor of electricity in the dark,but becomes conductive when exposed to light. After the belt or recordweb 16 has been exposed by high intensity light beam of the cathode raytube 11, the image formed thereon is developed at process station 19 inaccordance with well-known electrophotographic principles as describedby Carlson in U. S. Pat. No. 2,221,776.

In operation, the beam starts in the position adjacent roller 1. As thebeam writes lines 1, 2, 3, etc. and progresses toward the right, roller1 moves with it. As viewed in FIG. 1 a line of characters is writtenwhen the beam sweeps in a plane into the page or in a planesubstantially parallel to the axis of roller 1 and a page or characteris written as the beam sweeps from left to right. Roller 1 as well asrollers 2 and 6 are of sufficient diameter and made of a material suchas foam rubber having sufficient resiliency so as to apply firm contactto belt 16 with the face of cathode ray tube 11. The record web or-belt16 does not move across the face of the cathode ray tube 11 but rather adifferent portion of the record medium is pressed against the face ofthe tube in synchronism with the sweep of the tube beam. The rotation ofthe rollers 1, 2, and 6 is counterclockwise, while moving from left toright across the face of the CRT 11. Rollers l, 2 and 6 have a resilientor deformable surface and thus when they are pressed against the face ofCRT 11 a flat surface is formed on web 16 which presents a relativelylarge area for exposure of the record to the light of CRT 11. Also, thefrictional forces of the record web 16, the rollers and the tension onrecord web 16 applied by drive rollers 4 and 5 insure that record web 16is stationary during recording time.

When roller 1 moves to the position of roller 2, time has elapsed andthe following action has taken place in synchronism with the movement ofroller 1:

1. Roller 2 moves to the position previously occupied by roller 6.

2. Roller 3 moves down to a position below CRT 11 face to provide beltmaterial or slack between rollers 1 and 6 and then moves up above CRT 11face. Alternately, a vacuum column could provide the same motion asroller 3.

3. Roller 6 moves into the position previously occupied by roller 1.

4. Processing station 19 transfers images or develops thin transferimage to paper, cards, etc. from belt 16.

5. Belt 16 driven by rollers 4 and 5 moves away from the processingstation, asynchronously if necessary, when transfer is complete.

It is understood from FIG. 1 that rollers l, 2 and 6 are mounted uponsuitable support means such as a pair of parallel guide rails and guidedby a motor 56 from left to right. In this configuration sufficientclearance is provided for roller 3 so that it may pass through the guiderails to produce slack in record web 16 at the proper time. Theserollers rotate in a counterclockwise direction about their shafts and inso doing press an incrementing portion of belt 16 against the face ofthe CRT 11 in synchronism with the electron beam. U. 8. Pat. No.3,446,554 to Hitchcock et al. describes a similar web advance systememploying a bicycle chain drive in which the paper web is moved across aplaten by presenting discrete areas of the paper to be scanned by anoptical device. Upon reaching the right hand position the loop or slackformerly made by roller 3 is moved to the left hand position of cathoderay tube 1 l by the roller next in line to start pressing the beltagainst the face of CRT 11. During the time when the electron beam isblanked out development and transfer of the previously recordedinformation is accomplished at the processing station. Alternately,development and transfer of the recorded image may take place during thefollowing sweep of the electron beam. In this case, development andtransfer is always one time period behind the writing period. Rollers 4and 5 drive belt 16 downward past the processing station so that theinformation thereon can be transferred and a new writing surfacepresented to the face of CRT 11. At the same time, roller 3 now forms anew loop in belt 16 and the action is then recycled. The drive means forreceiving belt 31 is sent a driving signal from the control circuits sothat transfer is made simultaneously with the movement of belt 16 byrollers 4 and 5.

When the beam of the cathode ray tube progresses from the left to pointB the end of the page occurs. The beam in broken outline at point Ashows the past position of the beam. At this time roller 1 for example,can begin moving to the right. When roller 2 starts moving to theposition formerly occupied by roller 6, rollers 4 and 5 move so as toplace the belt into proper position for image transfer. As noted above,only that part of belt 16 from roller 1 on moves since part of the beltis always in contact with the face of the cathode ray tube. As a result,no time is lost waiting for the belt to move in full page stops betweenpages since the action takes place during writing.

Referring now to FIG. 2, there is shown the details of the processingstation. A portion of belt 16 is initially charged by electrode 18. Thenthe charged portion of the belt 16 is exposed in imagewise configurationby the light beam of cathode ray tube 11 as the light beam moves fromleft to right. The belt 16 is then passed over receptacle 20 whereproperly charged electroscopic powdered toner 22 is deposited on thelatent image areas of the belt by paddle wheel 21. The belt then passesbetween a grounded V backing plate 25 and transfer electrode 26 wherethe powder images are transferred to a receiving web 31. Receiving web31 is held in position against backing plate 25 by guide rollers 23 and24 and is fed from supply reel 27 to takeup reel 28. The transferredimages are next fixed to receiving web 31 by fuser 29. Belt 16 iscleaned of toner 22 by brush and the above cycle is repeated.

The foregoing description has been predicated on the assumption thatbelt 16 is comprised of a dielectric surface which is capable of holdingan initial electrostatic charge and which is discharged in imagewiseconfiguration upon exposure to the light beam of cathode ray tube 11. Itwill occur to those skilled in the art that other sensitized belts maybe employed.

FIG. 3 illustrates another embodiment of the record ing apparatuswherein recording or printing is undertaken in a vacuum 40. In thisembodiment a web 36 is fed from supply reel 34 to take-up reel 35. Whenthe fiber optic face plate 12 is removed from CRT 11 and the system isplaced in a vacuum the microprinting mode is improved. In this mode,processing at 39 may then be performed outside the vacuum. However,where belt 36 is a photoconductor and is the permanent record,processing may then be performed in the vacuum. Processing thephotoconductor in this manner results in an improvement in that higherresolu' tion is possible because the electron beam and energy isincreased by at least times. Alternately, the configuration of FIG. 3may ,be operated in a positive vacuum or air.

Rollers 32, 33, 37 and 38 as well as electrode 41 perform the samefunction as described in FIGS. 1 and 2. Moreover, the operation of FIG.3 is substantially the same as described with regard to FIGS. 1 and 2.The present invention is suitably unique in that printing can beasynchronous as is necessary in computer operation. For example, highspeed can be maintained since mechanical motion as such is not afunction that prevents beam writing. The fiber optic face platetransmits sufficient energy to allow the belt to be made of for exampleselenium, print 10,000 lines per minute and allow in excess of severalhundred bits (CRT light spots) per character.

Where it is desired to record in the micro-image mode fiber opticshaving a small diameter and a small CRT are used in lieu of the largerdiameter fiber optics and large CRT utilized for the full size imagingmode. For the intermediate size imaging mode fiber optics and a CRTbetween the above are employed.

It will be apparent to those skilled in the art that the presentinvention may be used generally in the field of recording and is -notlimited to the embodiments described. Also, other variations,modifications and adaptations of the present invention will be apparentto those skilled in the art, and such as come within the spiritand scopeof the appended claims are considered to be embraced by the presentinvention.
